To answer your first question, getting your post meta »bookauthor« this way will echo/display just that. If you are defining the variable $id in your code right – or you can do it like shown below. The code should answer your second question, how to insert your second title line to the product page via … Read more
This one is actually surprisingly simple; add this to your wp-config.php file and all automatic updates will be blocked when outside of the specified hours: // Suspend updates when outside of business hours, 9:00 AM to 5:30 PM $updates_suspended = (date(‘Hi’) < 0900 || date(‘Hi’) > 1730); define( ‘AUTOMATIC_UPDATER_DISABLED’, $updates_suspended ); You can also use … Read more
In functions.php: function mynewproduct(){ myfunction(); } add_action( ‘new_product’, ‘mynewproduct’ ); For more and the official documentation, refer here: http://codex.wordpress.org/Post_Status_Transitions
The reason the code posted is not working is that $post is not referencing the global $post variable, which is the goal here. Using get_the_ID() is a good way of accessing the ID associated with the current post. That’s how I’d suggest doing it, but there are other ways too: add_action ( ‘wp_head’, ‘hook_inHeader’ ); … Read more
For all admin pages and front end pages except individual post edit screens (wp-admin/post.php), ‘wp’ is the most reliable hook for getting the global values. http://phpxref.ftwr.co.uk/wordpress/nav.html?wp-includes/class-wp.php.source.html#l486 You can see there that it fires immediately after WP::main() fires WP::register_globals(). The problem with using things like post_results and get_posts is that it will run every time you … Read more
At the moment, it is not possible. When ‘pre_get_posts’ runs, is too late to stop WP_Query to perform a query. WordPress itself, when you try to query a taxonomy that does not exists, adds AND (0 = 1) to the WHERE clause of the SQL query, to ensure it returns no results very quickly… There’s … Read more
There is no filter that I know of that is meant to target individual shortcodes like you want. You can filter attributes with shortcode_atts_{$shortcode} though. You can hijack another shortcode by creating your own callback and registering it with the original shortcode slug. I think that is what you are probably going to need to … Read more
You can do this with the nav_menu_link_attributes filter. add_filter( ‘nav_menu_link_attributes’, ‘wpse156165_menu_add_class’, 10, 3 ); function wpse156165_menu_add_class( $atts, $item, $args ) { $class=”class”; // or something based on $item $atts[‘class’] = $class; return $atts; }
There is the filter: “views_plugin-install” (see here). You can find it in /wp-admin/includes/class-wp-plugin-install-list-table.php (currently) at line 226: $views = apply_filters( “views_{$this->screen->id}”, $views ); Use it like: add_filter( ‘views_plugin-install’, ‘my_filter’, 10, 1 ); function my_filter( $views ){ //Do your stuff return $views; }
As long as hooks don’t have anything hooked to them they are no-ops, that is do nearly nothing and have no considerable effect on runtime. It gets quite different when things are hooked and there are a lot of calls. Since you talk about customizing strings the good example would be gettext hook in core. … Read more
